In this episode of Once Upon A Time in Black History, host Tamara Shiloh shines a light on Valerie L. Thomas, the brilliant mind behind NASA’s “Illusion Transmitter” — a groundbreaking invention that paved the way for 3D imaging technology.

From her childhood curiosity in Baltimore to becoming one of NASA’s most innovative scientists, Valerie’s journey is one of persistence, imagination, and quiet revolution. As one of the few women—and even fewer Black women—in physics during the 1960s, she not only helped translate satellite data into vital Earth imagery but also reimagined how humans could see and share information.

Discover how Valerie’s creativity helped shape the world of imaging—on Earth and beyond—and how her legacy continues to inspire future generations of scientists and dreamers alike.
